SPECIFICATION forming part of Letters Patent No. 587,504, dated August3, 189'?.

Application filed April l '7, 1 8 9 6.

To all whom t may concern:

Be it known that I, EVAN J ONES, a citizen of the United States,residing at Creston, in the county of Union and State of Iowa, haveinvented certain new and useful Improvements in Sanding Attachments forLocomotives, of which the followingis a specification.

The object of my invention is to provide a simple, economical, andefficient mechanism for forcing sand out of the sand-box to a pointunder or adjacent to the driving-wheels of a locomotive by the use ofpneumatic pressure.

A further object of my invention is to provide an auxiliary mechanismwhereby the4 sand may be fed out of the sand-box to a point under thedriving-Wheels bygravity only; and the invention consists in thefeatures, combinations, and details of construction hereinafterdescribed and claimed.

In the accompanying drawings, Figure l is a transverse sectionalelevation taken through the sand-box of a locomotive; Fig. 2, ahorizontal sectional view taken on the line 2 of Fig. l; Fig. 3, a sideelevation of a portion of a locomotive with my improvements attachedthereto in position ready for use; Fig. 4, an enlarged sectional view ofthe compound valve, taken on line 4 of Fig. 2; and Fig. 5, a transversesection taken on the line 5 of Fig. 4.

In constructing my improvements and fitting them to a locomotive Iprovide a sandbox A, of the usual type and of any desired size andshape, and attach it to the body of a locomotive-boiler B by riveting itthereto or in any of the ordinary and well-known methods. Adjacent tothe lower side portions of the sand-box I provide deliverypipes C, thatlead therefrom to a point directly under the driving wheel or wheels D,so that as sand is delivered from the box it strikes the rail or railsadjacent to the under portion of the driving-wheels for the purpose ofenabling the same to obtain better traction on the surface of the track.

In order to feed the sand, as desired, in the box to the delivery-pipes,I provide what I term a compound valve7 E, arranged in the bottom of thebox and horizontally so as to provide a substantially horizontal passagee through the same and which opens atapoint adjacent to the bottom ofthe sand-box, as at Serial No. 587,945. (No model.)

e The other end is provided with an opening e2, which connects directlywith the delivery-channel e3, with which the deliverypipes areconnected. The compound valve is provided with a horizontally-projectingportion E', that practically covers the upper portion of theinlet-opening e', so as to prevent th'e sand from directly entering suchopening, or, in other words, keep the weight p of the larger portion ofthe sand off of such opening, but in such a manner as to permit the sandto enter a slot e4 between the projection and the main body of thevalve. This prevents the sand from being jarred or shaken out of the boxwhile the train is in motion. Arranged at the front part of thisprojecting portion E and substantially in line with the passage -e is aninjecting-perforation e5, in 'which is secured a pipeGr, that has itsopposite end connected with a source of iuidpressure-compressed air.This pipe is provided, as is shown to the left of Fig. 3, with a valveg., which may be operated to open or close connection with theair-reservoir G for the purpose of shutting off or admitting the desiredquantity of Huid-pressure, the action resulting in injecting the sandthat may be in the slot e4 into the passage e and forcing it downthrough the delivery-channel to a point underneath the driving-wheel.

The advantages of the structure are that the sand will not spill or rundown the channel without the use of the fluid-pressure, and the passagesand the arrangement of the inj ector are such that the valve may beoutside of the sand-box and the flow of sand be regulated to any degreerequired.

It is often desirable, especially in climbing or descending grades, tosave all of the fluidpressure for the purpose of the brake mechanism,and in such conditions it is desirable to have mechanism, operated,preferably, by hand, that will allow or permit of the sand being fed tothe track by the force of gravity only. In order to accomplish thisresult, I provide the compound valve with a second vertical passage E2,directly in line with the delivery-channel es, and in this opening I iita vertically-movable valve I-I, having its stem portion Z connected witha' rock-shaft H', this rock-shaft in turn being provided with abellcrank lever h havin@ an actuating-rod I IOO With its free endextending into the cab J of the locomotive, so that it may readily bereached by the engineer or iirelnan for the purpose of operating theValve l-I and admitting sand into the delivery-pipe or preventing itfrom entering such pipe.

The advantages of the entire structure are that the engineer at alltimes is furnished with a mechanism that permits him to control theoutflow of sand Without the use of pneumatic pressure, and at times,when de-` sired, pneumatic pressure can be used for forcing out desiredquantities of sand for the a substantially right-angular passage thevertical portion connecting with the deliverypipe and a horizontalportion opening adjacent to the bottom of the sand-box, a horizontalprojecting portion on the valve-casing covering the upper portion of theinlet-opening of the horizontal passage and provided with aninjecting-perforation substantiallyin line with the horizontal passage,amanuallyoperating valve` closing communication between the verticalopening and the sand-box, and a pipe connecting the injecting-passage ofthe valve With a source of fluid-pressurecompressed air-substantially asdescribed.
